int8

tests

Integer type that uses 1 byte per data element and can store values in the range -127 .. 127.

This type corresponds to int8_t in C/C++, int in python, np.dtype('int8') in numpy, and pa.int8() in pyarrow.

Most arithmetic operations involving this type will produce a result of type int32, which follows the convention of the C language.
